Suppose a researcher successfully produced a membrane composed of saturated triglycerides rather than from phospholipids. What characteristics would you expect the saturated triglyceride membrane to have?
A. hydrophilic molecules would easily pass through the membrane.
B. hydrophobic molecules would be attracted to the membrane.
C. the membrane would be fluid at room temperature
D. the saturated triglycerides would not form a bilayer.
Answers
Answer:
B. hydrophobic molecules would be attracted to the membrane.
D. the saturated triglycerides would not form a bilayer.
Explanation:
Triglycerides are molecules composed of a higher proportion of saturated fatty acid chains where carbons are connected by single bonds. Triglycerides are hydrophobes, i.e., they are nonpolar hydrophobic molecules. In this case, it is expected that hydrophobic molecules, including triglycerides, would be attracted through hydrophobic interactions (between water and hydrophobes). Triglycerides contribute to maintain the structure of the cell membranes by forming a lipid bilayer. Unlike phospholipids, triglycerides lack a polar group (phospholipids contain charged phosphate groups), and therefore triglycerides are unable to orient themselves in order to form a bilayer.
What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the tenth place and do not include units.)
Answers
Answer:
See Explanation
Explanation:
The question is incomplete as the diameters of the Willapa Bay urchins were not given.
However, I'll give a general way to solve this problem.
Average is calculated using:
[tex]Average = \frac{\sum x}{n}[/tex]
i.e. Sum of all diameters divided by the number of bay urchins.
The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.
10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm
Using the above data, the average is:
[tex]Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}[/tex]
[tex]Average= \frac{86}{10}[/tex]
[tex]Average= 8.6[/tex]

Which two phenomena are evidence that gravitational forces are attractive? Select two statements.
A. the rise and fall of the tides
B. atoms being held together in a molecule
C. a dropped object always falls toward Earth
D. microwaves passing through the atmosphere into space
Answers
Answer:
A. the rise and fall of the tides.
C. a dropped object always falls toward Earth.
Explanation:
Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.
Additionally, the gravity of earth makes it possible for all physical objects to possess weight.
The two phenomena which are evidence that gravitational forces are attractive includes;
I. The rise and fall of the tides: this is caused as a result of the gravitational force of attraction exerted by the moon on earth.
II. A dropped object always falls toward Earth: this acceleration is due to the gravitational force of attraction between the Earth and the object.

If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answers
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.

Living organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 4 options:
A. sugar
B. minerals
C. hydrogen
D. all of these
Answers
Answer:
A.sugar
Explanation:
In the process of phorosynthesis, the plants absorb energey from the sunlight, and with the water they have in the soil and the carbon dioxide they can absorb from the air, they´d produce carbohydrates or sugar and oxygen, in the chemical process of photosynthesys 6 molecules of water are mixed with 6 molecules of carbon dioxide, with addition of solar energy and form 6 molecules of sugar and 6 molecules of oxygen.

The artery that will eventually subdivide to form the posterior cerebral arteries is the _____ artery.a) basilarb) external carotidc) maxillaryd) superficial temporale) nternal carotid
Answers
Answer:
a) basilar
Explanation:
The basilar artery is an artery whose function is to supply of blood to the brain and central nervous system, thereby transporting oxygenated blood to the brainstem, cerebellum, and occipital lobes for maintaining normal brain function. This artery is 3 to 4 mm in diameter. The basilar artery is formed from the confluence of two vertebral arteries inside the cranium at the level of the medulla. The posterior cerebral arteries are formed by the bifurcation of the basilar artery, and they supply oxygenated blood to the occipital lobes and posteromedial temporal lobes.
